Re: [slurm-users] Restrict user not use node without GPU

[Paul Raines]

I do this via code in  job_submit.lua

function slurm_job_submit(job_desc, part_list, submit_uid)
    -- Must allocate GPU if on a GPU partition
    if (job_desc.tres_per_job == nil and job_desc.tres_per_node == nil) then
      if (string.find(job_desc.partition, "rtx8000")) then
        slurm.log_info("slurm_job_submit: for user %u, no GPU requested in 
rtx8000",
          job_desc.user_id)
        slurm.log_user("FATAL: you must request at least one GPU in the rtx8000 
partition");
        return slurm.ERROR
      end
    end
    return slurm.SUCCESS
end


Then set JobSubmitPlugins=lua in slurm.conf

I cannot find any documentation about what really should be in 
tres_per_job and tres_per_node as I would expect the cpu and memory
requests in there but it is still "nil" even when those are given.
For our cluster I have only seen it non-nil when GPUs are requested.

Dear all,

I am trying to restrict users not to use nodes without GPU but no luck.
Please help me with this.
Some users are accessing the GPU nodes and submitting the job(without GPU
), so I want to restrict such users not use nodes without GPU.

Thanks
